Headless Setup of Raspberry Pi Zero W (Raspberry Pi 3 Wireless) (macOS).markdown

#Headless Setup of Raspberry Pi Zero W (Raspberry Pi 3 Wireless) (macOS)

1. Formatt the Micro SD card - Open a terminal and type 'diskutil list'. Find your card and copy the disk name (For example: /dev/disk4). Format the card with diskutil eraseDisk ExFat temp disk4(Use your disk here)
2. Download Raspbian - wget https://downloads.raspberrypi.org/raspbian_lite_latest
3. Unmount the SD card - diskutil unmountDisk /dev/disk4 or whatever your disk path is
4. Mount the Raspbian image to the card - sudo dd if=PATH-TO-RASPBIAN-IMAGE of=/dev/disk4` or whatever your disk path is
5. Enable SSH on the Pi - cd /volumes && ls. You should see a boot partition from the SD card cd boot && touch ssh
6. Setup WiFi on the PI - While still in the boot partition of the card type nano wpa_supplicant.conf and enter network={ ssid="YOUR-SSID" psk="YOUR-WIFI-PASSWORD" }
7. Boot the PI - Unmount the card diskutil unmountDisk /dev/disk4 (or whatever your disk path is) and put it in the Pi, then power up the Pi
8. SSH Into the Pi - Find the Pi's IP on your network by running arp -a or using an app like LanScan and ssh into it ssh pi@YOUR_PIS-IP. THe default password is raspberry
9. Add your SSH key to the PI - While in the Pi run install -d -m 700 ~/.ssh. On you machine run cat ~/.ssh/id_rsa.pub | ssh <USERNAME>@<IP-ADDRESS> 'cat >> .ssh/authorized_keys'

Also, if you're using 'Stretch' you need to include the full wpa text in your wpa_supplicant.conf file:

wpa_supplicant.conf

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=US

network={
	ssid="your-network-service-set-identifier"
	psk="your-network-WPA/WPA2-security-passphrase"
	key_mgmt=WPA-PSK
}

Got this working on Mac with an SDXC 64GB card. Worked on OS X 10.13.4.

The first few steps should be slightly different:

• Download OS: https://downloads.raspberrypi.org/raspbian_lite_latest
• You should now have a .ZIP file. Unzip OS. You should now have an .img file.
• Format card: diskutil eraseDisk FAT32 TEMP MBRFormat /dev/disk3 // DOUBLE-CHECK DEVICE NAME

I think it is important to note that by saving your wpa_supplicant.conf with "YOUR-WIFI-PASSWORD" in step 6, your pi will store your wifi password in plain text. If security isn't a major concern, then ignore this, but in case you'd like to change this, I suggest you read the "Connecting with wpa_passphrase" section of this wiki article:

Hey Caleb i was wondering how can i assigned an Static IP Address to the PI once i set this one over the WIFI correctly?

How do you do this on a public network?

Hope this helps someone else...

I tried this and it wasn't working. I eventually figured out that my issue was that my WiFi router supports both:

• Wireless Network (2.4GHz b/g/n), and
• Wireless Network (5GHz a/n/ac)

Using a 5GHz a/n/ac network failed, but using the 2.4GHz b/g/n worked!
Make sure you're NOT using a 5GHz network for your ssid network name.
